404 KEPORfS OF THE INSPECTORS OF MiNES. [OfF. DoC.
to say that during- this j^ear it has drifted back into even a worse condition
than it was, notwithstaudiuof all the promises that it would be put
in better condition before mj^ next visit, but as a g-eneral rule on mj^
next visit I found a different mining-boss in charge, and this accounts
for mj' predecessor describing- it as being- worked on an "indefinite
system." The lower workings are still full of water and from present
appearances are likely to remain so. The ventilation is produced bj'^ the
heat radiated from the steam pipes and the temperature is so high on
the slope haulag-e way that it is almost impossible to travel it. Decem-
ber 4, 1891, I found tlie ventilation and drainage bad in No. 1 butt dip.
I requested the mining-boss, Mr. Henry Nay lor, to have them remedied
which he promised he would do if he could get the material. Altog-ether
this mine is in a very unsatisfactory condition. Forty new ovens have
been added to this plant, making 170 in all.
Blorrell Mine.—Owned by the Cambria Iron Company, but operated
by Isaac Taylor, lessee. Slope opening and worked on a good principle
for ventilation. My last measurement g-ave a volume of 65,280 cubic feet
at inlet and 14,000 feet at extreme dip working-s. Drainage and roads
gfood. Average number of persons employed inside, 225. All the provisions
of the mining law are carefully observed. Mining--boss. John
Yocum.
Mahoning 3Iine.—Owned and operated by the same parties as Morrell
and Atlas mines. It is a slope opening and fan ventilation with a volume
of 57,600 cubic feet in circulation. The condition of the mine has been
very much improved during- this year. A new pumping station has been
established and the steam pipes removed from the main haulage way
thereby making the mine a g-reat deal cooler and safer in everj^ respect.
The g-eneral condition of the mine is good, and the law well obeyed.
Mining-boss, David Walters.
Oliver Mines Nos. 1 and 2.—Located about one mile north of Uniontown,
Fayette county. Pa. Owners, Oliver Coke and Furnace Company,
Pittsburg, Pa.
The officials of the Coke Company are D. B. Oliver, president; Geo.
T. Oliver, vice president; William Jenkins, secretary; Fred. C. Keighley,
superintendent; C. B. Boss, mine-boss; John Schultz, machinist, and
Daniel J. Davis and Charles Watson, fire-bosses ; Wilkins & Davison,
constructing engineers.
Oliver Mine No. 1 is located on the extreme southern edge or line of
North Union township. The coal is reached by a shaft 12x26 feet out-
side measurements and 414 feet in depth The shaft is divided into
three compartments, two of which are for hoisting and one for ventilation
and exhaust steam, steam lines and water pipe.
The coal in this shaft is being developed or opened up on the four heading
system and when fully opened out will be ventilated without the use
of doors. In sinking this shaft it was designed to reach the lowest point
